Yes. And Jihadists would love any size of attack against the WH or Capitol Hill, just so they could brag that they were able to hit it.

Actually, a small plane packed with C4 would have to be extraordinarily lucky to do serious damage to the White House.

The White House is a pretty large building, and there are hardened parts to it.

Explosives can do alot of damage, but usually only in the immediate vicinity, planning for and using them takes alot of thought and practice.
